• A nyone who has experienced dizziness, seizures, loss of awareness, blackouts, or other
symptoms linked to an epileptic condition, or has a family history of such symptoms or
conditions, should consult a doctor before using iris recognition.

diagnostic, therapeutic, or preventative medical purposes.
For better iris recognition
The phone may not recognise your eyes when:
• s omething prevents the camera from getting a good view of your irises (e.g. glasses, low
eyelids, recent eye surgery, disease, dirt, damage to the camera, or excessive movement).
• t he lighting is very different from when you recorded your irises (e.g. direct sunlight).
Hold your device about 25-35 cm away from your face with the screen facing towards you.
